Abstract

The invention pertains to a method for coating polycarbonate moldings, characterized in that a molding compound (b) produced by hydrolytic polycondensation of an aluminum compound of an organofunctional silane and an oxide component is deposited in a thickness of 2 to 200 'mu'm on the surface of a molding of polycarbonate based on a diphenol of formula (Ia), wherein R1 and R2 are, independently of each other, hydrogen, halogen, preferably chlorine or bromine, C1-C8 alkyl, C5-C6 cycloalkyl, C6-C10 aryl, preferably phenyl, and C7-C12 aralkyl, preferably phenyl C1-C4 alkyl, especially benzyl; m is 4 or 5; R3 and R4 are, individually optional for each X independently of each other, hydrogen or C1-C6 alkyl, and X is carbon, provided that R3 and R4 are both alkyl on at least one X atom, and the compound is cured at a temperature of 135 to 180 degree C. The invention also pertains to the scratch-resistant polycarbonate moldings thus produced.
